State the laws of photoelectric emission.
- 
  There is a minimum cutoff frequency required for emission of electrons. Below this frequency, no electron emission occurs 
- 
  The total number of emitted electrons increases with the intensity of incident light 
- 
  Kinetic energy of the electrons emitted is dependent on the frequency of light and independent of intensity of light 
- 
  There are zero time lags between the incidence of the light beam and electron emission.
